With the growing popularity of Go many people are asking how to build a solid GUI. It’s design for concurrency and portability makes it a great match for cross-platform development. This talk shows how the Fyne toolkit is designed to help make beautiful and idiomatic native apps simply, using pure Go. This talk introduces the Fyne toolkit, it’s vision, architecture and it’s styling based on Material Design. We will explore the main features including canvas, widgets, application APIs and test support. Following this introduction we will show how to build a simple application that compiles for many different operating systems and platforms. Building on this there will be illustrations of more complicated applications that have been built with Fyne. We will wrap up with how the Fyne tools can be used to package graphical applications for macOS, Windows, Linux, Android and iOS. If you would like to build intuitive cross platform graphical apps that are quick to create and fast to run then this is the talk to see! Notes: This presentation can include live code examples if required, either through the playground or building on the local computer. Additional bonus if we can run an Android emulator on the presenting computer (my own computer is prepared in advance).
